Special requirements:                                         

  1. This proposal requires an upgrade of the Compton polarimeter (green laser,  300 µm micro-strips in electron detector).
  2. This proposal also requires the implementation of Flash ADCs in the HRS DAQ
  3. The LD2 target cells have to be equipped with 3 mil Be endcaps.
